WINDOW FRAME AND SASH.

SPEGIFI CATION forming part of Letters Patent No. 585,949, dated July 6,1897..

Application filed October 5, 1895.

To all whom it may concern.-

Beit known that I, FRANK E. BROWN, a citizen of the United States,residing at Concord, in the county of Merrimac and State of NewHampshire, have invented certain new and useful Improvements in WindowFrames and Sashes; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to windows of houses, steamers, railway-cars, orany windows from which it is desirable to exclude all the air possible,as also the dust and dirt.

WVindows invariably admit more or less air, dust, and dirt,whether it bethose of railwaycars, steamers, or private houses.

By the liberal use of outside windows houseowners who can afford theadditional expense can manage to keep out the greater part of winterwinds; but while double windows somewhat assist in keeping out the coldfrom a house they will not serve as good a purpose as a dust-guard, andeven what little good they might accomplish in this direction is notavailable, as outside windows are removed through the warmest and mostdusty seasons of the year, when the dust and dirt have easy access tothe house through the single sashes, which are of necessity made ratherloose in order to render them easy of operation.

In windows in steamers and cars (especially those of the latter, wheresash-weights are never used) the sashes cause frequent annoyance asidefrom their ready admission of dust, as they seem prone to stick andrefuse to respond to the eiforts of those who would open or close them.

The objects of my invention are to provide simple and inexpensive meansfor overcoming all the foregoing difficulties and to render suchimproved appliances applicable to sin-v gle sashes, thus doing away withthe inconvenience and expense of outside windows upon houses.

The invention will be fully set forth in the following specification andclaims and clearly illustrated in the drawings accompanying and forminga part of the same, of which- Figure 1 is a perspective view showing acar-window in which the sash is represented Serial No. 564,701. (Nomodel.)

in broken elevation and to which myimprovements are applied, Fig. 2being a sectional elevation of the same. Fig. 3 is a sectional plan viewillustrating my improvements as when applied to a car-window, and Fig.4.-is a similar view representing the application of my improvements toa house-window or any window which may be provided with an upper andlower sash.

Similar letters of reference designate corresponding parts throughoutthe several views.

A represents the sill, and a the side frames, of. the window.

B is the sash, and O the window-glass.

The vertical portions b of the sash B are beveled on one edge, as seenat b in Figs. 3 and 4, and on the vertical portion 0: of thewindow-frame are adjustable cleats D, having that edge adjacent to thesash beveled, as at cl, corresponding to the bevel b of the latter,slots d being formedat intervals in said cleat for the reception ofscrews 61 by which said cleat may be adjusted toward or away from awindow-sash, as maybe required.

Upon the opposite side of a sash cleats E are secured to the portions aof the windowframe, and in order that a gentle pressure of thewindow-sash against the adjustable cleat D may be maintained the cleatsE are recessed on their under side, as at e in Figs. 2 and 3, and withinthe recess are secured at intervals throughout its length suitablesprings F, which act upon bearing-strips G, resting for this purposebetween the springs and the window-sash and within said recess 6, thusinsuring an easy-working window-sash, as its slideway is yielding.

The sill A is provided with a double-inclined tongue at, its outsideedge being on an acute angle, while that portion which forms its top orinsideedge is obtuse, having reference in both cases to the verticalplane, the former angle being less and the latter greater than a rightangle, and the bottom horizontal edge of the sash B may be grooved toexactly project downward and fit the acute incline of said tongue C6.

It is characteristic of the improvement that the weight of the sashholds the inclined walls of the tongue and groove in close contact. Theobject of making one of the walls of the tongue approximately horizontaland the other approximately vertical, as shown, is that the weight ofthe sash may be sustained upon the former to obviate danger of splitting and to more effectually exclude water and dust by the latter. Theyielding slideways at the side of the sash cooperate by making acomparatively close joint without preventing the weight of the sash fromtightly closing the described joint at its bottom.

I am aware that a centrally-situated V- shaped groove has been formed ina sash to fit a similarly-shaped rib on a sill, and I do not claim suchdevice. The vertex of my groove is situated at one side of the centralvertical plane of the sash-bar to provide a bearing having a width ofmore than half said bar, and the longer side or bearing-wall of this issituated toward the inside of the window in order that the shorter side,which is more nearly vertical, may be adjacent the outer portion of thesill and adapted to more eifectually exclude rain, snow, or dust. Thesprings 13 cooperate in this result, but do not materially interferewith the direct downward bearing of the sash upon the obtuse incline.

IVhen my invention is applied to the upper and lower sashes ofhouse-windows, the top of the window-frame will be provided with atongue similar to that of the sill, and the upper sash will also begrooved or otherwise formed to closely fit it when said sash is raisedor,,closed, and in such case my improved beveled cleat or way willoccupy a position between the sashes, as seen at H in Fig. 4, with theyielding bearing-strips G, within the recessed cleats E, secured atopposite sides of the sashes, affording a good close joint. Thisconstruction of the adjacent horizontal portions of the window-frame andsash or sashes causes the latter to bear quite naturally against thebeveled cleat or cleats, and when properly adjusted the parts willassume the relative positions shown in Fig. 2, and longcontinued usewill only tend to increase the wind and dust proof qualities of myimproved window; and another advantage may be mentioned, to wit: Incar-windows or any wherein sashes are used without weights the tensionof the springs F may be sufficiently increased to cause them to bearwith so much force against the bearing-strips G that the sash willremain at any desired elevation without other support.

Having described my improvements, what I claim is 1. In a window, thecombination of a frame, asill havinga slope,a tongue at the upper edgeof said slope having inclined walls formed thereupon or attachedthereto, the outer incline being relatively narrow and making an acuteangle with the vertical plane and the inner incline being wider andmaking an obtuse angle to the said plane and a sash having adouble-inclined groove corresponding with that of said double-inclinedtongue, and springs F pressing the narrow inclines in close contact, allsubstantially as described whereby dust or water is excluded and thesash suitably supported in vertical direction.

2. In a window, the combination of aframe, a sill having a slope, atongue or rib at the upper edge of said slope having inclined walls, theouter incline being relatively narrow and making an acute angle with thevertical plane and the inner incline being wider and making an obtuseangle to the said plane and a sash having a double-inclined groove withits vertex in front of the cen tralvertical plane of the sash andfitting said double-inclined groove, whereby the width of thesash-bearing is increased and a more efficient obstruction to dust andrain is provided, and springs F and beveled cleats H, said springstending to force the sash against both the tongue and the cleat,substantially as described.

In testimony whereof I aiiix my signature in presence of two witnesses.
